BOTTLE CAP.

Application filed December 18, 1926. Serial No. 155,743.

My invention relates to bottle caps, and particularly to so called self-removing bottle caps of the type described in my application for Letters Patent filed August 18, 1926, Serial Number 1530,0541. It has for its objects to provide a new and improved means for removing and destroying bottle caps at one and the same operation, so as to preclude a repeated use. of the cap in closing the bottle, thus insuring untampercd contents to the consumer.

I accomplish the objects of-my invention as illustrated in the accompanying drawing, which forms a part of this specification and in which Figure 1 shows the topm-ember of my improved bottle cap, pre erably of metal. Figure 2 shows the stopper section, preferably of cork, adaptable for insertion in the cap shown in Figure 1. Figure 3 shows the lifting member, preferably of steel wire, the ends of which are adaptable for insertion between the stopper and cap and which function both as a lifter and. in conjunction with the grooves or slits in the cap hereinafter more particularly described, as means for mutilating the cap and rendering it unfit for future use. Figure. 4 shows an inner view of the assembled cap. Figure 5 shows the assembled cap in position on a bottle. Figure 6 shows the cap as mutilated after removal from the bottle.

Referring again to Figure 1, A shows the top of the cap. B shows the corrugations on the rim, into which corrugations the arms of the lifting member, shown in Figure 3, are shaped to fit. C and D show cuts. or preferably near cuts, in the corrugations against which the arms of said lifting member rest in use. Referring again to Figure 2, E shows the stopper member. Referring again to Figure 3, F shows the ends of the lifting member shaped to fit between the cap shown in Figure 1 and the stopper section shown in Figure 2. G shows that portion of the lifting member designed for pressure against the thumb of the human hand when it is desired to remove the cap from the bottle or container. The portion G, as shown, lies in a plane substantially parallel with the arms, and said portion G extends outwardly from the surface of the neck of the bottle. It will be understood that in removing the cap an upward pressure is exerted at E, causing the cap to readily lift. This pressure also forces said arms into the near cut construction is used). and rendermg it unfit for future use.. If desired the lifter member may be soldered or otherwise fastened to the body of the. cap, but for ordinary use the stopper member affords sufficient holding'force. A variation of my device is had by stamping the cap proper and lifting member from one piece of materlal, the crimping at the rim extending throughout the length of the lifting member and sufiieiently stiffening same for lifting purposes. In the latter event the cuts C and D are positioned adjacent to and in extension of the side lines of the lifting member.

When the cap is forced on the bottle, the ends of the wire members'form wedges to more positively hold the cap on the bottle against the force of the pressure within the bottle, as for instance that generated by a highly carbonated liquid.

It is obvious that those skilled in the art, may vary the details of construction and arrangement of parts without departing from the spirit .of my invention. I therefore do not limit myself to the above disclosure except in so far as is necessary in construing the following claims:

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States of America:

1. The combination with a crimped bottle cap having weakened portions in and through two relatively spaced crimps, of a wire member bent intermediate its ends to form a finger grip portion extending out from the neck of the bottle, and the respective ends being received in the respective aforementioned crimps with the weakened portions, thereby to remove. the cap on lifting the finger grip portion and at the same time rupture the weakened portions in and through the respective crimps,

2. The combination with a crimped bottle cap having weakened portions in and through two relatively spaced apart crimps, of a single wire strand bent intermediate its ends to form a finger grip portion, and the respective ends being received in the respective aforementioned crimps with the weak ened' portions thereby to remove the-cap on lifting the finger grip portion and at the same time-rupture the weakened portions in and through the respective crimps, the fincuts C and D, (breaking the seal in event ger. grip portion lying in'a plane substantially parallel with the ends to space the same from the surface of a bottle neck.

3. The combination with a crimped bottle cap having weakened portions in and through certain crimps thereof, of a wire member forming a finger grip portion, and the respective ends being received in the respective aforementioned crimps with the weakened portions, threby to remove the cap on lifting the finger grip portion and at the same time rupture the weakened portions in and'throngh the respective crimps.

4;. The combination with a crimped bottle cap adapted to be held against pressure within a bottle by the crimps in the cap, and having weakened portions in and through certain crimps thereof, said weakened crimps being spaced from each other,

ingreceived in the aforementioned crimps with the weakened portions and forming wedges between th. cap and the neck of the bottle when the ca is forced on the bottle thereby to hold is e cap more positively against the force of pressure within the bottle, said wire members adapted to be manipulated to rupture the weakened portions in and through the respective crimps to remove the cap.

In testimony whereof I afiix my signature.
